C-8Troubleshooting

■If you are using a Compaq SpeedPaq 56K or Rockwell-based 56k-flex modem in the managed server, make sure that you have upgraded the modem firmware to the latest version offered by the modem manufacturer. Early 56kflex firmware versions (before 1.12) incorrectly generate the data carrier detect signal (DCD) while the modem is reporting the connect string. This interferes with the reception of the carriage return sequence necessary to invoke the login prompt.

■The operating system may have recently accessed the modem. Integrated Remote Console regains ownership of the modem if no activity is detected for 60 seconds. Wait 60 seconds and try again.

■If the modem is not configured correctly in the operating system, the operating system may fail to communicate with the modem and periodically retry this operation. These periodic attempts gain ownership of the modem from Integrated Remote Console making it unavailable for login. Check for proper operation of the modem by temporarily disabling Integrated Remote Console. When proper operation with the operating system has been verified, re-enable Integrated Remote Console.
